Radars can detect projectiles at considerable distances, and larger projectiles give stronger reflected signals RCS.

The system is currently deployed by military forces around the globe. Tobyhanna’s Radar Center of Excellence rasar the largest and most comprehensive capability in the organic industrial base for all types of radar. By using this site, you agree to the Terms of Use and Privacy Policy.

Early counter-battery radars were generally used against mortars, whose lofted trajectories were highly symmetrical and allowed easy calculation of the launcher’s location. However, in low-threat environments, such as the Balkans in the s, they may transmit continuously and deploy in clusters to provide all-around surveillance.

This article includes a list of referencesbut its sources remain unclear because it has insufficient lcmt citations. By the early s, radar systems capable of locating guns appeared possible, and many European members of NATO embarked on the rradar Project Zenda.

It mounts on a tripod using lightweight antenna hardware, allowing for rapid emplacement and ease of relocation. The conical shaped beam of a traditional radar had to be pointing in the right direction, and to have sufficient power and accuracy the beam couldn’t have too large an angle, typically about 25 degrees, which made finding projectile quite difficult. Detection ranges depend on capturing at least several seconds of a trajectory and can be limited by the radar horizon and the height of the trajectory.

The test simulator is the only one in the Army. For more information about our LCMR counterfire radars, please contact us today. The additional problem was finding the projectile in flight in the first place. Its full azimuth coverage allows it to simultaneously detect and track multiple rounds fired from separate locations within a square kilometer surveillance area.


There is no other counterfire radar in the world as small, light, and affordable as the LCMR. Similar situation for the new GA10 Ground Alerter 10 [5] radar qualified and successfully deployed by the French land forces in several different FOBs worldwide. These effects are minimized immediately after launch, but the low angle makes it difficult to see the rounds during this time, in contrast to a mortar which climbs above the horizon almost immediately.

Purely ballistic low-angle trajectories are lopsided, being relatively parabolic for the start of the flight but becoming much more curved near the end.

In some armies, radars may have authority to send target details to counter-battery fire units and order them to fire, in others they may merely report data to an HQ that then takes action.

Of course, the trajectory has to be high enough to be seen by the radar at these ranges, and since the best locating results for guns and rockets are achieved with a reasonable length of trajectory segment close to the gun, long range detection does not guarantee good locating results. This was short-lived for unclear reasons, but the US embarked on Firefinder program and Hughes developed the necessary algorithms, although it took two or three years of difficult work.

They can filter out the targets of no interest e. Until about this relied on conventional artillery survey, although gyroscopic orientation from the mids helped. The latter could observe the splashes of water from missing shots, enabling corrections to be plotted. The Ku band has also been used. For non-parabolic trajectories, it is also important to capture a trajectory as close as possible to its source in order to obtain the necessary accuracy.

Modern radars usually record the target as well as the firing position of hostile artillery. They can detect and track anything in their field of view, providing they have sufficient computing power. Sign In Sign Out.

To produce accurate locations radars have to know their own precise coordinates and be precisely oriented. The Australian Army is using the system operationally. Michael Stevenson said, adding it’s easier to transport, set up, maintain and use than previous radar systems. Radars typically have a crew of 4—8 soldiers, although only one is needed to actually operate the radar.


The operator would watch for mortar bombs to pass through the slice, locating its range with pulse timing, its horizontal location by the location of the Foster scanner at that instant, and its vertical location from raadr known angle of the thin beam.

Instead of a conical beam, the radar signal was produced in the form of a fan, about 40 degrees wide and 1 degree high.

Modern radars typically give CEPs around 0. Low angle trajectories normally used by guns, howitzers and rockets were more difficult. This allows the radar to notify multiple batteries as well as provide early warning to the friendly targets.

In other circumstances, particularly counter-insurgency, where ground attack with direct fire or short range indirect fire is the main threat, radars deploy in defended localities but do not need to move, unless they need to cover a different area.

When compared to its expeditionary predecessor, it detects targets with flatter trajectories while calculating the point of origin more accurately from a greater distance.


Generally, the shells could not be seen directly by the radar, as they were too small and rounded to make a strong return, and travelled too quickly for the mechanical antennas of the era to follow. The first radars were developed for anti-aircraft purposes just before World War II. One technique was to deploy listening posts that told the radar operator roughly where to point the beam, in some cases the radar didn’t switch on until this point to make it less vulnerable to electronic counter-measures ECM.

However, with these figures long range accuracy may be insufficient to satisfy the Rules of Engagement for counter-battery fire in raxar insurgency operations. Since a parabola is defined by just two points, then lmcr a segment of the trajectory was not notably efficient. The cylinder-like radar structure electronically steers electromagnetic pulses across a degree protective envelope. Once RAM or improvised munitions are detected, the radar sends an early warning message indicating a round is incoming.
